I read the MS response to this as suggested. Their page fails to mention some things: 1. The "web bug"--more aptly called the transparent GIF exploit--has been known for some time. They are correct to state that it is not just a Word problem. However, most casual users of Word, like myself, would never expect such a thing embedded in a Word document. Now I am beginning to understand why I have received spam in the past that was sent attached as a Word document--highly unusual. 2. Those of us who are at least somewhat aware of security will be on our guard when on the web. It's a jungle out there. However, the sample Word document still performed as expected when I had it detached and opened it. For those with DSL or cable modems, web-connected LAN's, or who happen to be dialed in to their ISP at the time, this is most insidious. 3. I would expect that IE has distinct features to handle cookies (though I've never used it); the web page points this out. However, despite MS's best efforts to make it otherwise, there are other browsers such as Netscape and Opera--I saw no mitigation notes for those. 4. The overall tone of MS's response seems dismissive. It is not MS's job to educate the masses on the inner workings of the Internet. Still, a further discussion on what these transparent GIF's can do is warranted. DJH
